Zusammenfassung:	PURPOSE:To prevent the abrasion of valve seats by forming two lugs of a check valve on the suction passage of a cylinder and matching the center line direction of the lugs of the check valve with the peripheral direction of the cylinder. CONSTITUTION:A check valve 20 having two lugs 20a is provided on the suction passage 12 of a cylinder 9. Valve seats 21a are provided in the peripheral direction of the cylinder 9 of a check valve hole 21, and a check valve spring 17 is arranged on the suction passage 12. Since the valve seats 21a are provided in the peripheral direction of the cylinder 9, the contact area between the valve seats 21a and the lugs 20a of the check valve 20 can be made large, and the abrasion of the valve seats 21a can be prevented.
